Specification of Letters Patent.

Patented Apr. 1, 1919. 1

Application filed September 25, 1918. "Serial No. 255,714.

T 0 all whom it may concern Be it known that I, EDWIN GENTZLER, a citizen of the United States, residing at York, in thecounty of York and State of Pennsylvania, have invented certain new and useful Improvements in Sifters, of which the following is a specification, reference' being had to the accompanying drawings.

This invention relates to certain improvements-in sifters, and has relation more particularly to a device of this general character especially designed and adapted for use in connection with ashes taken from a coal burning stove or the like, and it is an object of the invention to provide a device of this general character having novel and improved means whereby the effective separation of the cinders and coal is obtained during a gravity flow of the ashes through the device.

It is also an object of the invention to provide a novel and improved sifter of this general character including a plurality of vertically arranged screening elements arranged in a manner whereby each of the upper screening elements discharges upon an element immediately below so that the sepa rated coal and cinders are discharged from the device substantially free from dust, and whereby the tumbling action of the ashes from one element to another results in the breakage of all except the hardest clinkers and the disintegration of the softer cinders so that only the coal accompanied by the hard cinders, will be separated.

The invention consists in the details of construction and in the combination and arrangement of the several parts of my improved sifter whereby certain important advantages are attained and the device rendered simpler, less expensive and otherwise more convenient and advantageous for use,

as will. be hereinafter more fully set forth.

The novel features of my invention will hereinafter be definitely claimed.

Fig. 3 is a'view in elevation with a portion broken away of my improved sifter' as 1 herein disclosed and with the removable wall or side omitted; 1

Fig. 4 is a vertical section on line IL-4 Fig. 3.

As disclosed in the accompanying drawings, C denotes a container or housing in its entirety, and which is provided with supporting legs .1 whereby the bottom 2 of the device is supported a predetermined distance above the surface upon which the device may rest. The top wall 3 of the container or housing at a marginal portion thereof is provided with a hopper 4 extending therethrough and discharging within the container or housing C. The hopper 4: extends substantially andentirely across the top wall 3 and into which the ashes to be separated are deposited. The side walls 5 of'the container or housing C adjacent the ends "of the hopper l have secured to their inner or opposed faces the cleats 6 extending downwardly on a predetermined incline and terminating a distance inwardly of the .removable or front wall 7. The walls'5 at the lower ends of the cleats 6 are connected by the horizontallyv disposed strip 8 provided at its top face with a longitudinally disposed groove 9 in which seats the lower marginal portion of a screening element S. The element S also rests upon the cleats 6 and the working surface of said element S is substantially flush and in continuity with the outer longitudinal wall a of the hopper 4: so that the ashes deposited within thehopper 4 will be discharged therefrom upon the screening element S and travel by gravity over said element.

The screening element S discharges upon a second or intermediate screening element S interposed between the walls 5 and positioned adjacent the removable wall 7 and disposed on a downward incline in a direction reverse to the inclination of the screening element S. The screening element S terminates a material distance below and The screening element S has its side marginal portions resting upon the cleats 10 suitably afiixed to the opposed or inner faces of the walls 5, and the lower marginalportion of the element S contacts with a strip 11 connecting said walls 5 and positioned at the lower end of the cleats 10.

P denotes a plate positioned below th screening element S at the side thereof ad 12 is cut out as at 1 1, and overlying said opening 14: is a screeningelement S upon which the screening element S discharges.

Theplate P has its side marginal portions resting upon the cleats 15 suitably secured to the inner or opposed faces ofthe walls 5 and the lower marginal portion of such plate seats within a groove 16 formed in the upper face of the lower beam or sill 17 disposed across the side'of the container or housing C with which the removable wall 7 coacts. The imperforate portion .18 of the plate P at the side thereof remote from the cut away portion 12 facilitates the discharge of. the separated coal and cinders through an eduction opening- 19 afforded by a suitable cut away or recess portion 19 formed in the lower end portion of the re movable wall 7.

Arranged within the container or housing C and secured at its upper marginal portion above the upper end portion of the screening element S is an imperforate plate or partition 20. This plate 20 extends downwardly in substantially a vertical plane and is continued by a downwardly -inclined extension 21 disposed toward the sill or beam 17, and secured at its lower end portion to a strip or beam 22 extending upwardly and laterally from the beam or sill 17 in a direction away from the cut away portion 12 of the plate P when said plate is in assembled position. The lower end of the'strip or beam 22 is secured to the inner face of the beam or sill 17 and the opposite or upper endportionof said strip or beam 22 is secured to the side wall 5 immediately adjacent the imperforate portion of the plate P and at a point adjacent the upper end of the cleat 15. The imperforate portion of the plate 18 rests upon this strip or beam 22 at thelower marginal portion of the opening or cut outportion 14. The arrangement of the beam 22 is such as to substantially define the lower-marginal. portion of said out out portion or opening 1 1.

Suitably secured to the inner face of the strip 8 is an imperforate partition plate 23, and the lower marginal portion of said said plate is in working assemblage. T denotes a trough underlying the screening element S and snugly fitting between the side walls 5,. andi'an end portion of said trough T directly above the cut out portion 12 is provided with a discharge opening 25 whereby said trough may discharge through the. cut out portion 12 upon thexextension plate P adjacent the cut away portion 12 of such plate. The ashes discharged from the hopper 4t first pass over the screening element Sand the minute particles pass through said element between the partitions 20 and 23 while the separated matter is deposited upon the second or intermediate element S. The minute matter passes through the element S within the trough T and is discharged, as hereinbefore recited, upon the extension 21 of the plate or, partition 20. The matter passing over the screening element S is. delivered directly upon the screening element S forming part of the plate P and any minute particles included in said material passes through the screening element S upon the extension 21. The ,separated matter such as coal passes over the imperforate portion 18 of the plate P and is discharged through the openingafforded by the recess 19 in the lowerend of the removable wall 7. If desired a suitable receptacle maybe positioned below such discharge opening as afforded by the recess 19 and which positioning of a receptacle is facilitated by the elevation of the container or housing C as attained by the supporting legs 1.

Minute matter delivered 1 upon the extension 21 oft-the plate or partition 20 is discharged from within the container or housing C by the chute or spout 27 which extends below the beam or sill 17 as is clearly illustrated in .Figs. .2 and 4. .A suitable receptacle may be arranged below the chute or spout 27 for receiving the material delivered thereby. It will also beself evident that the positioning or arrangement of the strip or beam 22-which is inclined downwardly toward the chute or spout 27 serves to materially facilitate the proper discharge of the material over said chute or spout. I

In view of the foregoing it will be self evident that the flow oftheashes or similar material to be separated by my improved sifter is obtained by gravity, and it has been fully demonstrated in practice that the screening elenients S, S, and S result in.

the separated particles such as coal and hard cinders to be delivered substantially free from all dust. It has also been found in practice that the travel of the material from one screening element to another results in T may be readily removed, one,independ' ently of the other, after the wall 7 has been withdrawn. By this arrangement a screening element which may have become unfit for use may be readily replaced, and which is also true of the trough T.

From the foregoing description, it is thought to be obvious that a sitter constructed in accordance with my invention is particularly well adapted for use by reason of'the convenience and facility with which it maybe assembled and operated, and it will also be obvious that my invention is susceptible of some change and modification without departing from the principles and spirit thereof, and for this reason I do not wish to be understood as limiting myself to the precise arrangement and formation of the several parts herein shown in carrying out my invention in practice except, as hereinafter claimed.
